Three different types of concrete mix design are as follows. There exist many algorithms that implement decision trees, such as classification and regression trees (CART) [31], C4.5 [33], Chi-squared automatic interaction detection (CHAID), and QUEST, which is the abbreviation of quick, unbiased, efficient, statistical tree [34]. Evaluate cement content from the water-cement proportion & additionally the final water content. Depending on how and where concrete is going to be used, its compressive strength and workability are determined, taking into account durability requirements. Pie charts show that for each mix design method, the designed mixes contain uniformly distributed strengths. Further, Hilal Erdal [30] used two-level and hybrid ensembles of decision trees for predicting high performance concrete compressive strength. In: Facolta di Giurisprudenza della R., editor. AT-XP or SET-XP for SET for Anchorages into Grout-Filled CMU & Unreinforced Masonry. The trained tree model can be viewed it its actual form, however, I only show the coarse tree model herein because the fine tree and the medium tree models are too dense to be interpreted properly.
